Move WordPress Admin Collapse Menu

Hi – I am trying to move the wordpress admin collapse menu button to the top admin bar but having trouble doing so.

This is what I have added to my functions.php file but it isn’t working properly.

function collapse_menu_button($wp_admin_bar){
$args = array(
'id' => 'collapse-button',
'title' => '<button type="button" id="collapse-button" aria-label="Collapse Main menu" aria-expanded="true"><span class="collapse-button-icon" aria-hidden="true"></span><span class="collapse-button-label">Collapse menu</span></button>',
'meta' => array(
'class' => 'collapse-button-label'
add_action('admin_bar_menu', 'collapse_menu_button', 0);

What do I need to edit in this so that it will work properly?

Thank you!

    Hey Boyd,

    The code you provided above actually works for me and adds the collapse menu in admin bar but the button itself doesn’t work.

    What I would suggest is trying with moving the item with some jQuery so it keeps its functionality.

    Adding this to your child theme functions.php should do the trick:

    function collapse_menu_button() { ?>

    <script type="text/javascript">
    jQuery( document ).ready(function() {
    var element = jQuery('#collapse-menu').detach();
    <style type="text/css">
    #wpadminbar #collapse-menu {
    width: 130px;
    list-style: none;
    .folded #wpadminbar #collapse-menu {
    width: 30px;
    list-style: none;

    <?php }
    add_action('admin_head', 'collapse_menu_button', 0);

    Best regards,
